The water-solubilizing ionic compound is suitably one which contains two isocyanate-reactive groups and an ionic group. In a typical Example (1), a prepolymer formed from toluene diisocyanate and a mixture of a polyoxypropylene diol and a polyoxypropylene triol is reacted with firstly the triethylamine salt of alpha,alpha-bis-(hydroxymethyl)propionic acid and then with triethoxysilylpropyl amine to form an isocyanate-terminated prepolymer which is then dispersed in water using a high-shear mechanical homogenizer. The dispersions may be used to form films or coatings and are particularly useful as impregnants for paper or leather. On curing by hydrolysis, the terminal silyl groups inter-react to form siloxane linkages.

Abstract: 1402710 Knitting COURTAULDS LTD 21 Nov 1972 [22 Nov 1971] 54098/71 Headings D1C and D1K A sleeved garment blank is formed by knitting a split body portion, on at least one bed of a two bed machine up to lines joining the sleeves, rearranging loops on the two beds so that they are in the same relative positions as they will occupy in the finished blank; and knitting onto these loops shoulders and tubular sleeves. The blank may be knit on flat or circular machines, and is without edge portions curled back on one bed to lie alongisde the main portion on the other bed. The preferred embodiments are knit on a conventional V-bed machine with mechanism for stitch transfer between and along the beds; or a machine having a two part second bed and mechanism for stitch transfer between beds. In the latter embodiment the V-bed machine includes a fixed bed 61, and second bed 62, 63 of two parts. The parts are movable towards or away from one another by lead screw 72. Body fabric 20 is knit up to the armpits 23, 24 and continues with two fashioned front panels 25, 26 and one rear panel 31, or vice versa. Loops along shoulder lines 27, 28, 32, 33 are retained on inactive needles. If rib or fancy stitch effects are included in the body all loops are transferred to bed 61. Loops of the last course are pressed off. End loops 97, 98 Fig 8a are transferred from needles 64c, d to the innermost needles 64a, b of the two part bed 62, 63. The beds are moved towards each other, Fig 8b. Loop transfer and bed movement continue until the shoulder loops either side of armpits 23, 24 are symmetrically disposed on the two beds, Fig 8c. U-shaped shoulder courses are knit onto the held loops, which are progressively activated, Figs 8d, e; and are followed by tubular sleeve courses, Fig 8f. If the blank is knit on a fixed bed machine, loop transfers between beds is followed by transfer of the group of loops along the bed. The blank may be finished by shaping the neck, 50, 51. The body portion may be knit wide enough so that edge wales 35, 36 overlap; alternatively the edges may be seamed.

In a variable displacement axial piston pump, the pistons 40 are held in engagement with a wobble plate 28 by a biasing member 42 of resilient metal or plastic material mounted on the drive shaft 14. The member has arms 50 with bifurcated outer end portions 52, the prongs of which straddle the piston rods 58, and transmit pressure indirectly to annular shoulders 54 in the piston heads 57 via elastomeric, e.g. polyamide, washers 64.

Abstract: 1485428 Photo-electric fluid analyzers BABCOCK & WILCOX CO 17 Dec 1974 [21 Dec 1973] 54369/74 Heading G1A A fluid analyzer comprises: a test chamber having first and second windows, each window having a pair of adjacent sections inclined to each other with surfaces in contact with fluid in the chamber; first and second similar units each associated with one window and having a radiation source and detector; means for directing a fixed measurement proportion of radiation from the first source so that some radiation passes through the first window, the chamber and the second window to be received by the second detector; means for directing a fixed reference proportion of radiation from the first source so that some radiation passes through the two sections of the first window to be received by the first detector; and means for energizing the sources cyclically and alternately. For absorption analysis of gases in a stack 2, opposed V-shaped windows 12A, 12B are each associated with a sealed unit 4, 6. One unit e.g. 4 has a lamp 8A, e.g. hollow cathode or mercury arc, filter 24A and collimator 26A directing a pencil of light towards a first beam-splitter 10A, so that a fixed proportion proceeds towards the window 12A, at least some continuing across the stack 2 and through window 12B; while another fixed proportion is diverted by the beam-splitter 10A, mirrors 14A, 16A and 18A and a second beam-splitter 20A at least some passing through both sections of the window 12A to be focused by a lens 28A on a pinhole diaphragm 3A to be received by a photo-cell 22A. Light crossing the stack from the similar unit 6 is diverted by the first beam-splitter 10A through the second beamsplitter 20A to the photo-cell 22A. Alternate illumination of the lamps 8A and 8B by a power supply and control unit 32 causes each photo-cell to respond with alternate reference and measurement signals. Signals from each photocell e.g. 22A, rendered logarithmic by an amplifier 46, are sorted by storage registers 52, 54 for comparison by a difference amplifier 60. Outputs from the difference amplifiers 60, 76 each representing the logarithmic ratio of a measurement to a reference signal, are summed by a summing amplifier 62 to give the logarithmic product of the two ratios, which is shown to represent the fluegas turbidity, with errors due to variable unknowns, i.e. window contamination source and detector and characteristics, eliminated. Constant errors due to characteristics of protected optical elements may be eliminated by calibration. In a second embodiment Fig. 2 (not shown) the two units (4, 6) are orientated along mutually inclined axes of a static vessel (88) for measuring scatter.

Abstract: 550,836. Isoalloxazine compounds ; vitamins. ROCHE PRODUCTS, Ltd., BERGEL, F., COHEN, A., and HAWORTH, J. W. July 16, 1941, No. 9001. [Class 2 (iii)] Isoalloxazine derivatives such as Vitamin B  2  are prepared by condensing 2-polyhydroxyalkylamino - 4 : 5 - dimethylazobenzene compounds with reduction products of alloxan such as alloxantin or dialuric acid. The reaction is effected in the presence of a mineral acid and preferably with the addition of a dehydrogenation-hydrogenation catalyst such as palladized charcoal; in its earlier stage a nitrogen or hydrogen atmosphere is advantageous. Examples describe the production of Vitamin B 2  2 (riboflavine) from 2-d-ribitylamino- 4 : 5 - dimethylazobenzene and alloxantin. Specifications 441,692 and 457,984 are referred to. The Provisional Specification describes also the use of 2-alkyl-4 5-dialkylazobenzene compounds as starting materials and states that when free hydrogen and the catalyst are present, the alloxantin may be replaced by alloxan.

As shown, a punch-card 7 is transported by a toothed wheel 26 driven by an electric motor through a pinion 25. The wheel 26 is mounted on a plate 28 pivoting about a drive shaft 23 for the pinion 25. Rotation of the transport wheel 26 is opposed by the torque reaction of a pinion 30 frictionally braked by an helical spring. The pinion 30 is mounted on a fixed frame member 21 so that rotation of the transport wheel 26 by the motor causes the wheel to engage the transport holes in the punch card and manual withdrawal of the card causes the wheel to rise and disengage from the transport holes. The limits of pivotal movement of the transport wheel are determined by a hole 29 in a frame member 11 through which a shaft 27 of the transport wheel passes. The control holes of the punch-card are engaged by levers 16, 16<SP>1</SP> actuating micro-switches 13, 14.
